Public bug reported: Apparently at random my screen will just lock up (although sometimes the mouse pointer will still move). It is exacerbated by using Google Hangouts and Skype but is not limited to using them.
The Xorg logs shows a load of errors and a stack trace. I can ssh into the box when this happens and see that the Xorg process is using 100% of a CPU core. This bug report is generated by sshing in to get the relevant data.
